Abstract
La présente invention concerne un réseau de capteurs de pression innovant et utile incorporant des éléments de capteur construits à partir d'un film électroconducteur jouant le rôle de substrat. Des exemples de films électroconducteurs (c'est-à-dire piézorésistifs) disponibles dans le commerce sont le Velostat et le Linqstat. L'invention concerne un dispositif pouvant être porté incorporant un réseau de capteurs de pression ayant des propriétés flexibles et une interface de matériau biocompatible entre les éléments de capteur et la peau d'un utilisateur. Le réseau de capteurs de pression utilise le film électroconducteur comme substrat et place une paire de conducteurs dans une configuration appropriée pour former des éléments de capteur individuels. Les éléments de capteur détectent le changement de résistance du film électroconducteur lorsqu'une pression est appliquée sur celui-ci. Les éléments de capteur peuvent être mis en oeuvre selon une configuration interdigitée ou opposée. Le réseau de capteurs comprend également une interface mécanique au-dessus des éléments de capteur pour transférer ou focaliser la pression appliquée sur le film électroconducteur.
